在电源设计中，经常会遇到驱动两个开关管的应用，如下图所示的典型应用。针对该应用SGMICRO（圣邦微）推出的MOS驱动芯片 SGM48000，可以满足该要求。图中的INA和INB为MCU发出的PWM控制信号。

SGM48000为双通道正相输入，能够提供最大2A的峰值电流，并且工作温度范围可达-40℃~+125℃，采用TDFN-2×2-8L和SOIC8两款封装，热阻为118℃/W。该驱动方案较为简易，同时可以pin to pin替换业界主流型号，设计难度低，开发时间短。本文列出行业内的两款主流型号MIC4424M、UCC27324和SGM48000对比表格以起到抛转引玉的作用。

从表格可知SGM48000的驱动能力较竞争对手稍低之外，其延迟时间非常短，因为其独特的电路设计提供了非常高速的驱动能力，通过匹配的上升和下降延时间来提高速度和驱动能力。这些匹配的延迟时间保持了输入到输出脉冲宽度的完整性，从而减少了时序错误和时钟偏移问题。通过非重叠驱动技术可以使MOSFET的动态开关损耗最小化。另外其具有很宽的工作电压范围（4.5V-26.5V），适应性更强。

SGM48000的特点及优势：

•增进的响应时间

•匹配的上升和下降时间

•减少双通道间的时钟偏差

•低输出阻抗

•在UVLO保护下，输出处于低电平状态

•高抗噪能力

•低电源电流

•宽工作电压范围：4.5V-26.5V

•-40℃至+ 85℃的工作温度范围，结温150℃

•ESD在HBM标准达6KV，MM标准200V

•采用绿色SOIC-8和TDFN-2×2-8L封装

对于SGMICRO（圣邦微）的SGM48000，世强有充足的备货及库存保障，明显的价格竞争优势，如果需要那就赶紧联系我们吧。

【应用】 SGMICRO SGM4547高集成度驱动芯片在激光测距电路中的应用

在激光测试产品电路中，一般采用5V产品供电，而激光发射管的工作电压值一般在15V以上，所以大多工程师采用Boost电路将电压升至15V后再供给发射管使用，另外激光管的工作频率一般都将近100kHz，所以普通的MOS管难以完成这么快的开关工作，目前比较通用的方式是使用高频率的MOS管产品再增加一颗MOS管驱动器产品实现高速开关，这样整个产品的发射电路就需要三颗主要产品：Boost电源芯片、MOS管、

【应用】高速精密比较器SGM8740协同驱动电路SGM48000应用于B超信号强回音判断

B超检查是超声波检查的一种方式,用超过20000Hz的信号对身体需检测部位发射，被检查部位如发生病变占位，身体对超声波回波强弱会与周边部位不同，回波信号与高速精密比较器进行比较，可以明显把强回音信号鉴别出来。SGMICRO的高速精密比较器SGM8740传播延迟仅45ns，输入失调电压仅0.9mV,非常适合对强回波监测。
